JPH0690629B2 - Sentence / voice conversion method - Google Patents

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sentence / speech conversion method used for automatically converting an input sentence of a word processor into a voice, collating it with an original by voice, voice output of message communication, or the like. Is.

2. Description of the Related Art FIG. 3 shows the configuration of a conventional sentence / speech conversion device. In FIG. 3, 1 is a keyboard for inputting kanji / kana mixed sentence codes, 2 is a kanji / kana conversion dictionary, 3
Is a kana-kana conversion unit, 4 is a syllable file, 5 is a voice synthesis unit, 6 is an amplification unit, and 7 is a voice output speaker.

In FIG. 3, a Japanese sentence entered with the Kanji and Kana mixed code entered from the keyboard 1 is searched in the Kanji-Kana conversion dictionary 2 by the Kanji-Kana conversion unit 3, and the reading and accent types are based on the information. It is given and converted into a kana code string. The voice synthesizing unit 5 searches the syllable file 4 for a syllable synthesis parameter corresponding to the Kana code string, and synthesizes a voice based on this. The synthesized audio signal is amplified by the amplifier 6 and output from the speaker 7.

Problems to be Solved by the Invention However, the kanji-kana conversion dictionary 2 in the above-described conventional sentence / speech conversion method includes a code that constitutes a word, a reading,
Information such as accent type and part-of-speech is stored, but adnominals written in hiragana (that, etc.) were not included. For this reason, the accent type of the bunsetsu containing the adnominal in hiragana was unnatural.

For example, when a sentence like the first sentence example is input, it is converted as shown in (the second sentence example).

(First sentence example) It has not been decided who will carry out the survey of the book.

But when humans occur, The accent type is given as in.

As in the above-mentioned conventional example, in the sentence / speech conversion method in which the dictionary does not have the information of adnominals written in hiragana, the accent different from that when human is generated is given, and the naturalness and intelligibility of the sentence deteriorate. Had.

The present invention eliminates the above-mentioned conventional drawbacks, and an object of the present invention is to eliminate unnaturalness of converted voice and improve the intelligibility of sentences.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention adds information of adnominals written in Hiragana to a dictionary, and searches this dictionary for Hiragana that precedes Katakana or Kanji. do it,
If identified, it will be combined with the subsequent Katakana or Kanji accent.

Operation Therefore, according to the present invention, a sentence including a continuum written in Hiragana can be converted into a natural and highly intelligible voice.

Example An example of the present invention will be described below. In the present embodiment, accent information of adnominals composed of hiragana characters such as “that” and “what” is added to the conventional kanji-kana conversion dictionary 2. For hiragana that precedes katakana or kanji, search the hiragana adjunct dictionary. If the word is identified as a continuum, the accent is combined with the subsequent word in katakana or kanji. For example, the first
In the example sentence, Is accented as in. As a result, the (first sentence example) is given an accent like the (third sentence example).

Similarly, (4th sentence example) becomes like (5th sentence example).

(Example 4) This bike is in that house.

The following is an example of the accent combination rule in this embodiment.

When a katakana or kanji noun follows after a type 1 accent noun, such as, is combined so that the whole becomes a type 1 accent.

When a noun of katakana or kanji follows after a noun of type 0 accent, such as, when the accent of the subsequent noun is type 0, the whole is set to type 0. Bind up to the accent position.

FIG. 2 is an explanatory diagram of the accent type (Sanseido: quoted in the Shinmei Kokugo Japanese Dictionary Third Edition), and FIG. 1 is a schematic flow chart of the accent combination process in this embodiment.

EFFECTS OF THE INVENTION The present invention has a dictionary of adnominals described in Hiragana as described above, and based on the information of this dictionary, the adjuncts and the subsequent Katakana or Kanji noun accents are combined. It has the effect of giving a natural accent close to occurrence.
